ST. LOUIS (KMOX) — A golf ball used by Phil Mickelson that he used to shoot a 12-under-par 60 in a round of golf recently was invented in St. Louis.

Its Callaway's ERC Soft golf ball, and it was invented by local entrepreneur Ray Barrett and Dr. Carl Bassi, who is a professor and director of research at UMSL's College of Optometry.

Ray Barrett told KMOX that the Triple Track lines on the ball are red, green, and blue because those are the easiest colors humans see.

"What we saw is that the three lines help you improve your aim," Dr. Bassi told Charlie Brennan. "There's a scientific basis of why it does that's based on what's called 'vernier acuity.' Our eyes are much more sensitive to alignment if we have these three lines we're using."

Mickelson tied his career-low 12-under 60 in the opening round of the Desert Classic at La Quinta Country Club in California on Jan. 17, 2019.
